Something is amiss when the check engine and service engine soon lights come on. Depending on the make and model of your car, you’ll see a different icon. It could be something minor, like a loose gas cap, or it could be something more significant, like a problem with the fuel system. When the light is on, you should bring your car in as soon as possible to get it checked.
A serious problem may be present if the service engine soon or check engine light is flashing. An engine misfire that causes the issue could harm the catalytic converters. It is highly advised that you have your car serviced right away if your check engine light is blinking.

What the Service Engine Soon Light Means
The check engine light and the service engine soon light are frequently confused. The check engine light serves as an alert to potential problems with your emissions or exhaust systems. A loose gas cap or more serious concerns, including a potential engine failure, may cause the service engine soon light to illuminate.
Unstable Gas Cap
A loose gas cap is one of the main causes of the “service engine soon” light coming on in your car. If the cap was not tightly reinstalled after the gas tank was filled, it may fall loose soon after.
The “service engine soon” indicator turns on when the cap comes loose after a specified amount of time.
This is made possible by the engine control module (ECM), whose main duty is to guarantee that your car runs as efficiently as possible. The ECM controls your car’s emissions and checks for any irregularities in the air-fuel mixture.
It first pinpoints the precise issue before conducting an internal test. When that occurs, you can either buy an OBD II scanner and perform it yourself, or you can visit your local service center for assistance in clearing the memory.
Service Engine Soon Light for Nissan Altima – Diagnosis
The service engine soon light on your Nissan Altima serves as a warning that a problem has been found with the car. OBDII codes, which are easily accessible through a decent code scanner, are used by all automobiles manufactured in 1996 or later. A service engine soon light that is flashing indicates an urgent situation.
You must read these trouble codes if your service engine soon light is on to determine what is wrong with your Altima. Even so, the existence of an engine issue is not always indicated by the trouble codes. The gearbox, ABS, oxygen sensors, etc. can be at fault.
What does my Nissan’s “service engine soon” light mean?
All vehicles respond differently to a variety of internal and external circumstances. The gas cap breaking loose is one typical cause of the service engine light turning on in a Nissan vehicle. When you fill up your gas tank and don’t correctly and tightly screw the cap back on, this may occur.
It will take several cycles after the gas cap is knocked off for the light to turn off. When the internal mechanisms determine that the system is functioning properly, the evap system will do a self-test. The engine control module, often known as the ECM, ensures that your car is operating at its peak efficiency. It manages the air-fuel ratio and regulates emissions for the vehicle.
The test will be carried out after the ECM is able to identify the precise conditions required. The memory can then be cleared at your neighborhood auto shop; fortunately, most shops offer this service free of charge. You can get a code reader, which will essentially carry out the same function as the auto worker, if you’d like to be more independent.
Low fluid levels are another potential cause of the service engine light. Checking the levels of your transmission fluid, brake fluid, windshield fluid, and engine oil should be your primary priority. You should check your car for leaks after checking all of the levels.
Determine if the issue is serious or not once you have identified the problem, or if you are having trouble figuring out what is wrong. If you are doubtful or if the service engine light is flashing, you should immediately stop driving or make every effort to reach the nearest service facility. In order to pinpoint the precise problem, the technician will be able to monitor your car using a computer and validate the diagnosis by consulting your owner’s handbook.

m Wayne Powell An emission-related error may be the cause of the SES light being on. If you follow the directions in your handbook or those found at the links below, you can get the codes without leaving your car because it can figure out why the engine light is on. After you have obtained the code(s), the first link can inform you of their identity.
Procedure for ECM diagnostics and reset:
– After three seconds, turn the ignition key to the ON position. (Never start the vehicle.)
– In less than five seconds, fully depress and release the accelerator pedal five times.
– Hold off for exactly seven seconds. Until the SES light flashes, depress the accelerator pedal completely for ten seconds.
– Let go of the gas pedal, then begin counting the flashes to get the four-digit trouble code.
The first digit of the code is indicated by long flashes (0.6 seconds); record the first digit by counting the blinks from one to nine. Zero is shown by ten blinks.
The following three numbers are presented one after the other in the same order, but with faster blinks (0.3 seconds) and a 1.0-second break in between each digit.
Use the links below for further explanation if necessary. Some auto parts retailers, like as Pepboys, Nappa, Advanced Auto Parts, etc., also provide free code reading services. These men are often quite competent and can direct you to the problem. Good fortune.
Given that the car senses a problem, this is a common error. A handheld computer can be plugged into the automobile at the majority of auto parts retailers (Autozone, Advanced Auto, O’Reilley’s, etc.) to verify the specific problem code that is turning on the service engine soon light. They will be able to tell you what your automobile is detecting as wrong with that error code.
Agreed. However, in addition to the “check engine” and “service engine” lights, many cars also include an additional indication light for oil that flashes.
What does it imply when you reset the ecm according to the instructions above and receive the code yet the “Srvc. Eng. Soon” light doesn’t blink as it should? I drive a Nissan Sentra from 2002. I repeated the instructions four times, with the same outcome each time.
Since I performed a multiple pedal ECU reset, my 2002 Xtrail has been unable to start for nearly four months. The code 1123 indicates that the fuel pump is operating, but there are no sparks, and the injection system appears to be operating without a computer signal. Does anyone know how to remedy this?
What does the 2012 Nissan Altima’s service engine soon message mean?
When the check engine light on your 2012 Nissan Altima starts to flash, it implies there is an urgent issue that has to be fixed, and your Nissan should be brought in right away. Usually, a serious engine misfire that causes unburned fuel to leak into the exhaust system is indicated by this blinking light.
Is the Nissan check engine light the same as the service engine soon light?
Many people are unsure of what each of these lights means, and the check engine light and the service engine soon light are frequently confused for one another. We’ll describe how distinct they actually are despite the fact that they appear to be similar.

Since Karl Benz originally unveiled his Benz Patent Motorwagen, automotive technology has advanced significantly. In fact, the notion that computers are essentially controlling our cars in today’s computer-driven society shouldn’t be shocking. In order to assure the precise right operation of your vehicle’s numerous systems and components, they regulate and track their performance. They even notify the driver when the automobile needs repair or maintenance. While technology hasn’t yet given our cars voices of their own (a la Kitt from Knight Rider), it has made it possible for them to communicate in other ways, such as through a series of backlit symbols that appear in the instrument cluster of your car, such as a “check engine” and a “service engine” light.
What sets off the service engine soon light?
The Service Engine/Check Engine When there is a problem with the fuel system, ignition, transmission, or emissions, a warning light will soon come on. This indicator does not merely indicate that you require routine maintenance.
Does AutoZone have an upcoming service engine light?
AutoZone scans check engine lights, right? AutoZone can identify codes from the check engine light, yes. If you’re unsure of why your engine light came on, visit your neighborhood AutoZone so that one of our staff members can use our free Fix Finder service to identify the problem.
When the service engine soon light is on, can you drive?
Is It Safe To Drive With The Service Engine Soon Light On? It is acceptable to drive when the service engine soon light is on. The light typically indicates a problem with your car, though it may not necessarily be significant. Driving with the light on, though, could occasionally harm your car or result in an accident.
How serious is the service engine soon light?
The service engine soon light indicates that your engine needs servicing and should be done as soon as possible. It doesn’t imply that the engine has malfunctioned or even that a meltdown is about to happen. It does, however, imply that you should schedule a visit with your mechanic as soon as possible to identify the cause of the issue and get the car fixed, if required.
If your service engine soon light illuminates while you are driving, you should stop as soon as you can to assess the condition and do a few quick tests. It’s possible that the issue is as straightforward as a missing or improperly-fitting gas cap because the sensors that activate the service engine soon light are frequently triggered by an issue with the emission control system.
As soon as you are off the road safely, thoroughly inspect the gas cap to make sure it is securely fastened. The emission sensors and the service engine soon light may be activated if the gas cap is not correctly sealed.
You may also experience issues with your most recent gas fill-up, which will turn on the service engine soon light. It is a fantastic spot to start your research if you recently purchased gas and then suddenly noticed that your service engine soon light is on.
Start by inquiring if there have been any new issues with the service station staff. There’s a good likelihood that other vehicles were also impacted if there was water or other pollution in the gas.
Try driving until you exhaust a couple of gallons of gas before topping off the tank with fresh fuel from a different service station if the automobile appears to be operating normally. You should schedule an appointment with your mechanic and have the vehicle checked out straight away if the vehicle’s performance has been affected.
The oxygen sensor, a mechanism that measures the manner in which unburned oxygen is released into the atmosphere, is among other issues that could turn on the service engine soon light. Ignoring a malfunctioning oxygen sensor might cost you hundreds of dollars in damage to your catalytic converter. That is just another justification for having a competent mechanic examine the service engine soon light as soon as feasible.
Having said that, if the service engine soon light is on solid and not flashing, you can generally drive safely while it is on. If your service engine light is on and flashing, you should stop right away, make a roadside assistance contact, and arrange to have your car towed to the shop.
Any dash light that comes on might be unsettling, but one with the term “engine” in the title can be extremely unsettling. However, you can react more correctly and make a wise and informed decision after you are aware of what the service engine light does and what it actually implies.
